Storage Arrangement
BACKGROUND
1. FIELD OF THE INVENTION
The present invention relates to a storage arrangement with a rack receiving
space and a
movement space. The rack receiving space includes at least one movable rack
and the
movement space contains a movement device which interacts with the at least
one rack. The
movement space is arranged above the rack receiving space in the direction of
gravity.
2. DISCUSSION OF BACKGROUND INFORMATION
DE 10 2016 010 288 Al and DE 10 2018 105 778 B4 describe storage arrangements
in which
racks are moved by transport vehicles, wherein the transport vehicles travel
on the ground and
thus lift the racks from below.
DE 10 2006 025 876 Al describes a container which houses a power-operated
storage system,
the load receiving means of which are embodied from multiple racks that are
connected to one
another via at least one drive train and each have multiple shelves arranged
one above the other
which circulate horizontally. This arrangement concerns racks that are
connected to one another
in a circulating manner.
In order for it to be possible to move racks of the arrangements described
above, the racks must
be moved by transport vehicles, wherein the transport vehicles must reach
under the rack in
order lift the rack. An elaborate programming, control, and positioning of the
transport vehicles
is necessary for this purpose, so that the respective transport vehicle can
assume a suitable
position for lifting the rack without said rack falling over. Furthermore, the
ground must always
be free of objects, since the transport vehicles which are loaded with a rack,
could begin to tip
if they run over such objects, wherein the loaded rack can fall over. In this
case, not only are
objects problematic, but also media such as oils, water, refrigerant, or the
like. If a transport
vehicle gets onto media of this type, the traction between the drive of the
transport vehicle and
the ground is reduced, so that the rack cannot be securely transported.

Though the solution of the circulating rack described in DE 10 2006 025 876 Al
does avoid the
difficulties with the transport vehicles, objects must be manually placed into
storage in the
permanently installed circulating racks, which is both time- and labor-
intensive.
SUMMARY
Embodiments are directed to a storage arrangement that achieves a secure and
flexible transport
of racks. In particular, the storage arrangement includes a rack receiving
space and a movement
space, in which the rack receiving space includes at least one movable rack,
and the movement
space contains a movement device which interacts with the at least one rack.
The movement
space is arranged above the rack receiving space in the direction of gravity
and the movement
device is releasably engaged with the at least one rack.
The storage arrangement of the type named at the outset is characterized in
that the movement
device is releasably engaged with the at least one rack. In this manner, the
movement device,
which is arranged in a movement space above the rack receiving space, can
interact with the
rack, wherein this interaction is carried out in the rack receiving space and
in the movement
space. The interaction involves the receiving, moving, and setting down of the
rack by the
movement device. This has the advantage that messes on the subsurface, such as
objects that
have fallen out of the racks or liquids such as oil, water or the like, for
example, are passed over
so that such soiling of the subsurface has no effect on the transport or a
movement of the racks.
Furthermore, the movement device interacts with the rack in an upper region of
the rack, for
example, so that the rack cannot fall over.
In one exemplary embodiment, the rack receiving space is equipped with racks
through an
opening, wherein a rack is transferred, for example, to a transfer position
inside of a rack
receiving space, so that the movement device transfers the rack into the rack
receiving space
from this transfer position. A rack can furthermore be removed from the rack
receiving space
via the transfer position. Thus, in this exemplary embodiment, racks can be
loaded outside of
the rack receiving space in order to subsequently transfer the racks into the
rack receiving space.
In another exemplary embodiment, the movement device moves the racks within
the receiving

space, wherein the racks can be organized according to a predetermined
sorting. The movement
device thereby moves one single rack at a time, so that the sorting of the
racks is carried out
iteratively. This sorting is carried out, for example, with what is referred
to as a sliding puzzle
principle, or sliding storage principle, wherein in said principle the maximum
number of racks
located in the rack receiving space corresponds to the maximum capacity minus
one or more
racks. In this exemplary embodiment, this means that one or more rack spots
are kept free. To
sort the racks, a rack that is adjacent to the free rack spot is moved into
said spot. This results
in a new free rack spot, into which another rack can be moved, for example.
This enables a
sorting with the greatest possible space utilization of the rack receiving
space.
In another alternative embodiment, all rack holding spots of the rack
receiving space are
occupied with racks so that a maximum degree of loading of the rack receiving
space is
achieved.
Because the movement device is releasably arranged with a rack, the movement
device can, in
order to move the rack, engage with said rack. Once the movement of the rack
by the movement
device is complete, the movement device releases from the rack, so that the
movement device
can be freely moved, for example in order to interact with a different rack.
As a result, the
movement device can interact with different racks. A high flexibility is thus
obtained.
The movement device preferably comprises a positively guided lifting unit that
can be moved
along two movement axes arranged at an angle, preferably at essentially a
right angle, to one
another, wherein the lifting unit can be moved perpendicularly to the two
movement axes. As
a result of this arrangement, the lifting unit can be moved over each rack
spot of a rack receiving
space. The positive guidance makes it possible to know which position the
lifting unit is located
in at all times. Furthermore, the lifting unit is guided and can thus be moved
free of slippage.
The positive guidance can thereby comprise a positioning unit, for example.
The angle of the
movement axes can be adapted to the layout of the rack receiving space. For
example, in a
rectangular receiving space, the movement axes are arranged at a right angle
to one another.
"At a right angle" thereby essentially corresponds to a 900 angle.

The lifting unit, which can be moved perpendicularly to the two movement axes,
permits a
lifting of the at least one rack in a lifting direction, wherein the lifting
direction is preferably
arranged against the direction of gravity. To set down the rack, the lifting
unit moves the rack
downward in the direction of gravity.
In one exemplary embodiment, the lifting path of the lifting unit can be
limited to a defined
length, so that the lifting unit can have accordingly large or small
dimensions. This allows a
lightweight lifting unit, as a result of which the costs can be minimized.
The at least one rack preferably includes a receiving geometry which
releasably interacts with
a lifting geometry of the lifting unit of the movement device. In order to
move the rack, the
receiving geometry and the lifting geometry of the lifting unit are brought
into engagement. As
a result of this engagement, the movement device interacts with the rack. The
engagement is
thereby achieved through a movement of the movement device, in particular of
the lifting
geometry of the lifting unit. With this arrangement, the costs are minimized
since additional
actuators can be omitted.
In one exemplary embodiment, the receiving geometry and the lifting geometry
interact with
one another through a positive, non-positive, or frictional engagement that is
temporary. This
means that it can be formed and severed. For this purpose, a positive
engagement with the
receiving geometry of the rack is achieved by a movement of the movement
device, in particular
of the lifting geometry of the lifting unit. Once the positive engagement has
been produced,
the rack can be moved. The positive engagement can also be severed again by a
movement of
the movement device, in particular the lifting geometry of the lifting unit.
The positive
engagement allows a secure transport of the racks since, as a result of the
positive engagement,
a relative shifting between the receiving geometry and the lifting geometry is
avoided.
Preferably, the lifting geometry can be moved beneath the and/or under the
receiving geometry
in the direction of gravity. This enables, through a lifting of the lifting
geometry against the
direction of gravity, a lifting of the rack by the receiving geometry attached
thereto. The
arrangement is thus kept simple, which further minimizes the costs.

Preferably, the lifting geometry comprises a seeking geometry and the
receiving geometry
comprises a locating geometry. With the seeking geometry and the locating
geometry, the
lifting geometry is clearly positioned relative to the receiving geometry. As
a result, the rack
can be set down in a defined position on the one hand, and the rack can be
lifted and moved at
defined receiving points of the receiving geometry due to this arrangement on
the other hand.
This enables a secure transport and a secure movement of the rack.
In one embodiment, the locating geometry of the receiving geometry is embodied
as a funnel-
shaped arrangement into which the seeking geometry can be guided. For this
purpose, the
seeking geometry is for example embodied as a mandrel, in particular with a
tip. This enables
a simple guiding of the seeking geometry into the locating geometry.
Preferably, the receiving geometry comprises a first securing geometry
arranged outwardly
from the rack, which securing geometry is releasably engaged with a second
securing geometry
of a receiving geometry of an adjacent rack in a securing position. The
securing position of a
rack describes a position in which the securing geometry of a first rack is
engaged with the
securing geometry of a second rack. In this securing position, the securing
geometries are
releasably engaged. The engagement can be severed, for example, with a lifting
movement of
the rack by the lifting unit. In the securing position, the racks stabilize
one another reciprocally,
whereby an inadvertent tipping or falling-over of individual racks is avoided.
In one exemplary embodiment, the first securing geometry comprises a
projection which is
engaged with a recess of the second securing geometry in the securing
position. For this
purpose, the securing geometries are arranged externally on the respective
receiving geometry.
The projection and the recess of the respective securing geometry constitute
simple, easy-to-
manufacture manifestations that are cost-effective.
In a further embodiment, the releasable engagement of the first securing
geometry is realized
with the second geometry through a dovetail-shaped connection. In this manner,
a stable
locking, in multiple spatial directions, of the adjacent racks is enabled in
the securing position.

Preferably, at least a boundary of the rack receiving space comprises at least
one holding
geometry that interacts with a securing geometry of the at least one rack. A
boundary of the
rack receiving space can be embodied, for example, by a wall, a fence, a door,
or the like. The
rack receiving space is arranged within this boundary. On the side of the
boundary that faces
in the direction of the rack receiving space, at least one holding geometry is
arranged which
temporarily interacts with a securing geometry of the at least one rack. The
holding geometry
is thereby adapted to the securing geometry. As a result, the at least one
rack is secured against
falling over or a movement in relation to the boundary of the rack receiving
space. This
arrangement prevents an unwanted movement of the rack. Furthermore, the
position of said
rack is defined by this arrangement. This simplifies the organization and the
handling of the
racks. Because of the securing of the rack on the holding geometry of the
boundary by the
securing geometry, it is furthermore prevented that said rack shifts and thus
interferes with the
movement of another rack by the movement device.
Preferably, in a lifting position in which the rack has been lifted by the
lifting unit, the securing
geometry of a first rack can be moved past the securing geometry and/or
receiving geometry of
a second rack in a securing position. The second rack is thus located in a
securing position
described above, while the first rack has been lifted by the lifting unit and
is thus located in a
lifting position.
For this purpose, in one embodiment columns of the racks comprise a notch
beneath the
receiving geometry and/or securing geometry, wherein the notch extends from
the outside in
the direction of the respective adjacent column and/or in the direction of the
middle of the rack.
In a further exemplary embodiment, the lifting position of the first rack is
determined by a
limited lifting height. In this manner, the recess, such as the one described
for example, can be
limited at the rack or the securing geometry and/or receiving geometry thereof
in the direction
of gravity. As a result of this arrangement, the first rack, which is arranged
in a lifting position,
can be moved past the second rack without portions of the securing
geometry/receiving
geometry of the second rack impeding the movement of the first rack.

Preferably, the at least one rack has a rectangular layout with a length
direction and a width
direction, wherein a column is provided in each corner region, with the
receiving geometry
being arranged on at least one column in an upper region thereof in the
direction of gravity.
The length direction and the width direction each extend perpendicular to the
extension
direction of a column. The length direction and the width direction are
thereby arranged
perpendicularly to one another. Through the arrangement of the receiving
geometry in an upper
region of the column, it becomes possible for the lifting device or the
lifting geometry to interact
with said receiving geometry. Because the receiving geometry is arranged on
the upper region,
a falling-over of the rack in a lifting position is avoided.
For example, rack shelves are arranged on the columns, which rack shelves are
arranged spaced
apart from one another in the direction of gravity. Stored goods can be
arranged on these rack
shelves, wherein the stored goods can be removed from the rack shelves and put
down thereon.
Preferably, the receiving geometry extends in the length direction and/or in
the width direction
towards one of the adjacent columns, preferably in the length direction and
width direction,
particularly preferably essentially towards the middle of the rack. As a
result of this
arrangement, a portion of the receiving geometry protrudes along the length
direction and/or
width direction, in particular towards the interior of the rack. This permits
an engagement of
the lifting geometry in the receiving geometry. The receiving geometry thereby
faces in the
direction of at least one of the adjacent columns. Furthermore, this
arrangement makes possible
a projection that can be approached from below by the lifting geometry. This
simple geometry
is cost-effective.
Preferably, a portion of the lifting geometry overlaps a portion of the
receiving geometry of the
at least one rack in the lifting position. As a result of this arrangement,
the lifting geometry can
interact with the receiving geometry once a corresponding position of the
movement device, in
particular the lifting device and lifting geometry, relative to the rack has
been reached.
Furthermore, due to the overlap, the use of additional actuators, servomotors,
or other
- 7 -

Date Recue/Date Received 2022-03-03
controlling elements can be is avoided so that the arrangement can be realized
with little effort.
Preferably, the lifting geometry can be moved between two adjacent columns of
the at least one
rack. As a result of this arrangement, the lifting geometry is located beneath
the receiving
geometries of racks that are arranged in a securing position. A lowering of
the lifting geometry
during the transfer of a rack from the securing position into a lifting
position is thus avoided,
since the lifting geometry is already arranged between the columns and beneath
the receiving
geometry and is thus appropriately positioned. As a result, the amount of time
for transferring
a rack from a securing position into a lifting position and vice versa can be
reduced.
The floor of the rack receiving space preferably comprises at least one
securing device for the
at least one rack. Through this securing device, the rack can be secured
against an unintended
movement out of a securing position. This prevents a falling-over or a
movement of the rack,
whereby the secureness of the rack receiving space or the storage arrangement
is increased.
In one exemplary embodiment, the securing device comprises an arrangement
which prevents
a shifting or movement of the rack perpendicular to the direction of gravity.
The rack can be
inserted into the securing device against the direction of gravity by the
lifting unit, and can be
removed from said securing device.
Preferably, the lifting unit can be moved on linear axes. With linear axes,
which also comprise
a measuring device, for example, the lifting unit can be moved in a defined
manner.
Furthermore, this enables a quick and easy design of the movement
possibilities of the lifting
unit. The development costs and manufacturing costs are thus minimized.
The storage arrangement is preferably mobile. This enables a use of the
storage arrangement
in different locations and under different circumstances. A high flexibility
of the storage
arrangement is thus obtained.
In one exemplary embodiment, the storage arrangement can be arranged in a
container, for
example, so that at a destination point the container or the racks can be
unloaded in a
- 8 -

Date Recue/Date Received 2022-03-03
corresponding order, wherein the unloading order can differ from the loading
order. The racks
are thereby moved and re-sorted accordingly by the movement device during
transport. This
reduces the removal time.
In a further exemplary embodiment, the storage arrangement can be arranged in
a vehicle, in
particular in a delivery vehicle. Racks with stored goods or transport goods
can thus be placed
into storage in the delivery vehicle prior to the start of a trip. The
movement device transfers
the racks from a transfer position into the rack receiving space via the racks
and can be removed
up until a defined rack position within the rack receiving space. While the
delivery vehicle is
en route to a destination, the racks are sorted such that the driver of the
delivery vehicle can
directly access the stored goods, transport goods or packaged goods, such as
parcels, that are to
be delivered. As a result of this, a time-intensive searching of the stored
goods that are to be
delivered is no longer required.
On the way to a next destination point, the racks are furthermore organized
such that a
corresponding parcel can be removed from a rack. For this purpose, the storage
arrangement is
arranged in a transport space of the delivery vehicle.
A service space is located inside of the transport space, which service space
permits access to
one or more rack spots within the rack receiving space. For delivery, the
movement device
places respective racks in these rack spots so that the driver can remove
parcels from these
racks. Here, a costly search of the stored goods by the driver is also no
longer necessary.
In a further exemplary embodiment, a manual storage spot system is located in
the transport
space of the vehicle next to the storage arrangement. Bulky goods or other
transport goods can
be stowed in this manual storage spot system. The delivery vehicle can thus be
used in a more
flexible manner. To remove the racks from storage from the delivery vehicle,
for example at
the end of a trip, back at the transport center, the racks are moved to the
transfer position by the
movement device inside of the rack receiving space, wherein from this rack
removal-from-
storage position the rack can be manually removed from the rack receiving
space by a driver or
another person. This allows a quick removal of the racks from the delivery
vehicle.

In another further exemplary embodiment, the racks comprise casters so that
the racks can be
rolled. This enables a manual movement of the racks outside of the rack
receiving space, for
example by people. A high flexibility is thus obtained.
Embodiments are directed to a storage arrangement that includes a rack
receiving space; and
a movement space. The rack receiving space includes at least one movable rack
and the
movement space may contain a movement device that interacts with the at least
one rack. The
movement space is arranged above the rack receiving space in a direction of
gravity, and the
movement device is releasably engaged with the at least one rack.
In embodiments, the movement device can include a positively guided lifting
unit movable
along two movement axes arranged at an angle to one another, and the lifting
unit may be
movable perpendicularly to the two movement axes. The two movement axes can be
arranged
at essentially right angles to each other. Further, the at least one rack may
include a receiving
geometry which releasably interacts with a lifting geometry of the lifting
unit of the
movement device. The lifting geometry can be movable beneath the receiving
geometry in
the direction of gravity. Still further, the lifting geometry can include a
seeking geometry and
the receiving geometry comprises a locating geometry. The receiving geometry
may include
a first securing geometry arranged outwardly from the rack, the first securing
geometry being
releasably engaged with a second securing geometry of a receiving geometry of
an adjacent
rack in a securing position. Moreover, at least a boundary of the rack
receiving space can
include at least one holding geometry that interacts with a securing geometry
of the at least
one rack. In a lifting position in which the rack has been lifted by the
lifting unit, a first
securing geometry of the rack can be movable past at least one of a second
securing geometry
and a second receiving geometry of a second rack in a securing position. The
at least one rack
has a rectangular layout with a length direction and a width direction, in
which a column is
provided in each corner region, with the receiving geometry being arranged on
at least one of
the columns in an upper region thereof in the direction of gravity. The
receiving geometry
can extend in at least one of the length direction and the width direction
towards an adjacent
column. The receiving geometry may extend essentially towards a middle of the
rack. A

portion of the lifting geometry may overlap a portion of the receiving
geometry of the at least
one rack in the lifting position. The lifting geometry can be movable between
two adjacent
columns of the at least one rack in a securing position.
In accordance with other embodiments, the floor of the rack receiving space
can include at
least one securing device for the at least one rack.
According to other embodiments, the lifting unit may be movable on linear
axes.
In accordance with still yet other embodiments, the storage arrangement can be
mobile.

DETAILED DESCRIPTION
The particulars shown herein are by way of example and for purposes of
illustrative discussion
of the embodiments of the present invention only and are presented in the
cause of providing
what is believed to be the most useful and readily understood description of
the principles and
conceptual aspects of the present invention. In this regard, no attempt is
made to show structural
details of the present invention in more detail than is necessary for the
fundamental
understanding of the present invention, the description taken with the
drawings making apparent
to those skilled in the art how the several forms of the present invention may
be embodied in
practice.
Fig. 1 shows a vehicle 1 with a driver's cab 2 and a transport space 3. A rack
receiving space 5
and a movement space 4 are arranged in the transport space 3. Multiple racks 6
are arranged in
the rack receiving space 5. In the movement space 4, a movement device 7 with
a lifting unit
8 is provided. The transport space 3 furthermore comprises a manual storage
spot system 9. A
driver operates the vehicle 1 and the storage arrangement. In order for the
driver 10 to be able
to access the rack receiving space 5, a service space 11 is provided between
the driver's cab 2
and the rack receiving space 5, from which service space 11 the driver 10 can
access the rack
receiving space 5 or the rack 6 located therein. The driver 10 can reach the
service space 11
through a passage from the driver's cab 2, which passage is not illustrated.
Furthermore, the
service space 11 can comprise a door through which the driver 10 can reach the
outside from

the service space 11. This is likewise possible from the outside into the
service space 11.
Fig. 2 shows multiple racks 6 that are engaged with one another through
securing geometries
13 arranged on receiving geometries 12. The racks comprise columns 14 on which
rack
compartments 15 are arranged. On an upper region of the columns 14, receiving
geometries 12
with securing geometries 13 are arranged. Furthermore, the racks 6 are
arranged in securing
devices 16 arranged on the floor. The racks 6 furthermore comprise casters 17.
Fig. 3 shows a top view of rack 6. In each corner region of the rack 6,
receiving geometries 12
with securing geometries 13 are arranged. The receiving geometries 12
furthermore comprise
a locating geometry 18. The locating geometry 18 is in this case embodied as a
through hole.
The securing geometries 13 comprise two embodiments that can interact with one
another. A
first embodiment comprises the securing geometry 13 with a projection 13A
which can be
releasably engaged with a recess 13B of a second embodiment of the securing
geometry 13. A
securing geometry 13 can thereby comprise a projection 13A and a recess 13B.
Fig. 4 shows a movement device 7 with two first linear axes 19 and two second
linear axes 20.
The lifting unit 8 is arranged on the second linear axes 20. The lifting unit
8 furthermore
comprises a lifting geometry 21 that can thereby be moved perpendicularly to
the two linear
axes 19, 20. Furthermore, the lifting unit 8 can be moved along the second
linear axis 20,
wherein the second linear axis 20 can be moved along the first linear axis 19.
The first linear
axis 19 is thereby arranged in the direction of travel of the vehicle 1, and
the second linear axis
20 is arranged transversely to the direction of travel of the vehicle 1.
Fig. 5 shows the lifting unit 8 with the lifting geometry 21. A seeking
geometry 22 is arranged
on the lifting geometry 21. Through a lifting mechanism not illustrated, the
lifting geometry
21 can be moved in the direction of gravity or perpendicularly to the first
and second linear axis
19, 20.
Fig. 6 shows the lifting unit 8 with the lifting geometry 21, wherein the
lifting geometry is
- 13 -
J 203 P 136 EP
Date Recue/Date Received 2022-03-03
arranged between columns 14 of a rack 6 beneath the receiving geometry 12. It
can clearly be
seen that the lifting geometry 21 partially overlaps the receiving geometry
12. To lift the rack
6, the lifting geometry is moved upwards in the direction of gravity, so that
the lifting geometry
21 is engaged with the receiving geometry 12. The locating geometry 18, not
illustrated in this
Fig., thereby interacts with the seeking geometry 22 so that a positively
engaged, releasable
connection between the lifting geometry 21 and the receiving geometries 12 is
present. The
position in which the rack 6 has been raised by the lifting geometry 21 is
hereinafter referred to
as the lifting position.
Furthermore, a notch 23 on the columns 14 can be seen in Fig. 6. The notch 23
essentially
describes an indent of the column 14, so that the two sides of the column 14
facing outward are
inwardly offset by a certain distance. The notch 23 makes it possible for a
rack 6 in the lifting
position to be able to be moved past another rack 6 in a securing position.
The securing position
describes a position in which the rack 6 is not engaged with the lifting unit
8 or the lifting
geometry 21, but rather the securing geometry 13 of the rack 6 is engaged with
another securing
geometry 13 of a second rack 6 and/or with a holding device, not illustrated,
on a boundary, not
illustrated, of the rack receiving space 5, and/or the rack 6 in a securing
position is engaged
with a securing device 16.
Furthermore, in Fig. 6, a pass-through position of the lifting unit 8 or the
lifting geometry 21 is
illustrated. The lifting geometry 21 can be moved in the direction of gravity
beneath the
receiving geometry 12, wherein the lifting geometry 21 is moved between the
columns 14 of a
rack 6.
The seeking geometry 22 and the locating geometry 18 are brought into
engagement during the
transfer of the rack 6 from the securing position into the lifting position.
In the lifting positions,
a positive engagement is thus present between the receiving geometries 12 of
the rack 6 and the
lifting geometry 21. Through the seeking geometry 22 and the locating geometry
18, a secure
hooking-in of the lifting geometry 21 on the corresponding receiving
geometries 12 is achieved.
A shifting of the lifting geometry 21 relative to the corresponding receiving
geometries 12 is
thus prevented.

In Figures 7A ¨ 7D, a placement-into-storage process of a rack 6 in the rack
receiving space is
illustrated. In Fig. 7A, a rack 6 is moved into the rack receiving space 5 by
the driver 10, for
example. The driver 10 thereby positions the rack 6 in a transfer position in
the rack receiving
space 5, as is illustrated in Fig. 7B. Fig. 7C shows how the rack 6 is
transferred from the transfer
position into a designated rack spot. For this purpose, the movement device 7,
in particular the
lifting unit 8, interacts with the rack 6. The driver 10 can then, as
illustrated in Fig. 7D, position
another rack 6 in the transfer position. The cycle starts from the beginning.
To remove a rack 6 from storage from the rack receiving space 5, the rack 6 is
positioned in the
transfer position by the movement device 7, in particular the lifting unit 8.
There, the rack 6 is
released by the movement device 7 so that the driver 10 can remove the rack 6
from the rack
receiving space 5.
In Figures 8A ¨ 8D, the principle of a sliding storage system is elucidated.
The sliding storage
system follows the same principle as a sliding puzzle. The rack receiving
space 5 thereby
comprises a certain number of rack spots. One rack 6 can be arranged in each
rack receiving
spot. In order for it to be possible to relocate or move the arranged racks 6,
one rack spot must
be kept free. Adjacent racks 6 can be moved into this rack spot. In this
manner, the organization
of the racks 6 within the rack receiving space 5 can be iteratively changed.
For this purpose,
the movement device 7 first moves the lifting geometry 21 into a position of a
rack 6 that is
arranged next to the free rack spot 26. The lifting device 8 then, in
combination with the lifting
geometry 21 and the receiving geometries 12, lifts the rack out of the
securing position into the
lifting position. This is illustrated in Figure 8A.
The rack 6 in the lifting position is subsequently transferred into the free
rack spot 26 by the
movement device 7. The securing geometries 13 of the surrounding racks 6 are
thereby at the
height of the notch 23, so that the securing geometries 13 of the racks 6 of
the securing position
do not collide with the rack 6 in the lifting position. This is illustrated in
Figure 8B.
In Fig. 8C, the way in which the rack 6 is transferred from the lifting
position into a securing
- 15 -

position is illustrated. For this purpose, the lifting unit 8 lowers the
lifting geometry 21, and
thus the rack 6, in combination with the receiving geometries 12. The rack 6
is then located on
the formerly free rack spot. The free rack spot and the relocated rack 6 have
thus switched
spots.
The lifting unit 8 can then proceed further and relocate a rack 6 that is now
arranged adjacent
to the new free rack spot 26. This is illustrated in Figure 8D.
In Fig. 9, an exemplary integration of the storage system in the vehicle 1 is
illustrated. The
service space 11 is arranged between the driver's cab 2 and the rack receiving
space 5.
Furthermore, a manual storage spot system 9 can be arranged in the service
space 11. From the
service space 11, the driver 10 can furthermore access multiple racks 6. These
racks 6 are
located in a removal position 24. The driver 10 can, through a laterally
arranged door 25, exit
the service space 11 to the outside or enter the service space 11 from the
outside.
Furthermore, the sliding storage system being implemented is illustrated in
Fig. 9. The rack
receiving space 5 comprises a free rack parking spot 26. An adjacent rack 6
can be relocated
into this free rack parking spot 26. In this manner, the positions of the
individual racks 6 can
be changed in succession.
In the rear region of the transport space 3, an additional manual storage spot
system 9 can be
arranged. This manual storage spot system 9 is accessible from the outside
through an
additional door 25.
Fig. 10 shows a further implementation possibility of the storage arrangement
in a vehicle 1.
The rack receiving space 5 thereby fills the entire transport space 3 of the
vehicle 1. Here, no
rack spots are provided in the region of the wheel wells 27. This is the case
if the wheel wells
27 protrude into the transport space 3. If no wheel wells 27 protrude into the
transport space 3,
additional rack spots can be provided in these locations.
Below, the functioning of the storage arrangement will now be described on the
basis of the
- 16 -

illustrated vehicle 1 within the scope of a parcel delivery. At a starting
station, for example a
parcel center, racks 6 are loaded with parcels to be delivered. For this
purpose, both the parcel
and also the rack 6 can be identified by a corresponding barcode, wherein the
parcel is assigned
to a corresponding rack 6. The racks 6 loaded with parcels are grouped
together for a particular
route and are ready for pickup by the driver 10 and his vehicle 1.
At the start of his shift, the driver 10 drives his vehicle 1 to a loading
station of the parcel center
in order to transfer the racks 6 prepared for him into the rack receiving
space 5. To do so, the
driver 10 pushes the rack 6 into the transfer position within the rack
receiving space 5. From
there, the movement device 7 takes over the rack 6 on the designated receiving
geometries 12.
Inside of the rack receiving space 5, the movement device 7 moves the rack 6
to a designated
position. At this position, the movement device 7 puts down the rack 6 so that
securing
geometries 13 interact with holding geometries, not illustrated, of the
boundary of the rack
receiving space 5. Furthermore, the rack 6 is inserted into securing devices
16 provided on a
floor of the rack receiving space 5.
In the intervening time, the driver 10 can transfer another rack 6 to the
transfer position.
Once the movement device has transferred the rack 6 that was placed into
storage first to the
target position thereof, the movement device 7 puts the rack 6 down. Then, the
movement
device 7 moves the to the rack 6 now located in the transfer position. There,
the lifting unit 8
lists the rack 6 and moves it to a predetermined position. This position is,
for example, adjacent
to the rack 6 that was placed into storage first. After arriving in this
position, the movement
device puts the rack down such that the securing geometries 13 of the two
racks 6, the rack
placed into storage first and the second rack 6 placed into storage, interact
with one another.
The driver 10 can then transfer additional racks 6 into the rack receiving
space 5 in the same
manner.
The order of the loading of the racks 6 does not matter, since they are sorted
or arranged by the
movement device 7 during a trip to the various destination points. Racks 6
with parcels that
- 17 -
J 203 P 136 EP
Date Recue/Date Received 2022-03-03
are delivered first can thereby also be transferred into a removal position by
the movement
device 7.
The rack receiving space 5 thereby holds a maximum number of racks 6, wherein
one rack spot
26 must be kept free for the sliding storage system.
Once all racks 6 have then been transferred into the rack receiving system 5,
the driver 10 can
start his trip. On the way to the first destination, the racks 6 are sorted
such that the driver 10
can access the parcel that is to be delivered. For this purpose, the
corresponding rack 6 is
transferred into a removal position 24. From the service space 11, the driver
10 can access the
rack compartments of a rack 6 that is located in a removal position. The
driver 10 thus removes
the parcel that is to be delivered and hands it over to a receiver. The driver
then drives to the
next destination.
In the intervening time, between the departure from the first destination to
the arrival at the
second destination, the racks 6 are sorted in the rack receiving space 5 such
that the driver 10
has access to the next parcel that is to be delivered. The corresponding rack
6 is also transferred
into a removal position 24 for this purpose.
This procedure is repeated until the driver 10 has delivered all parcels, or
until his trip is
finished. The driver 10 then drives back to the starting point.
After arrival at the parcel center, the movement device transfers one rack 6
after the other to
the transfer position, from which the driver 10 can remove the rack 6 from the
rack receiving
space 5.
While the racks 6 are arranged in the rack receiving space 5, adjacent racks 6
secure one another
reciprocally with the securing geometries 13. Each rack 6 thus remains in its
inherited position
until it is lifted and moved by the movement device 7. An inadvertent shifting
or movement of
the racks 6 can thus be avoided. The interaction of the racks 6 with the
movement device
arranged thereabove in the direction of gravity furthermore permits a quick
and easy re-sorting
